Keen to join the mile-high club? By 2045 you might not even need a plane ticket.

A mile-high monster would infiltrate the Tokyo skyline in the next 30 years, if plans for an ambitious project were to go ahead.

The futuristic ‘Next Tokyo 2045’ development features a behemoth 1700m skyscraper, dwarfing the current tallest structure in Japan that currently peaks at the 634m Tokyo Skytree.

The Sky Mile Tower would be the tallest building in the world at double the height of Dubai’s Burj Khalifa, which currently holds the title, and five times Australia’s biggest – the Gold Coast’s 337m Q1 tower.

The tower has a potential occupancy of 55,000 people and would feature 20m-high multi-level open-air sky decks every 320m, as well as shops, restaurants, hotels, libraries, gyms and health clinics.

But the height isn’t the only striking feature of the development.

Architects have designed Next Tokyo 2045 as a series of hexagonal archipelagos on reclaimed land in Tokyo Bay.

Although “very ambitious”, the Sky Mile Tower is entirely feasible, according to Ulster University Belfast honorary visiting Professor Chris Abel.

“There is the engineering know-how, but the question is why do it,” he told The New Daily.

“Tokyo needs [development in Tokyo Bay], it is going to grow, it is going to need expansion, whether or not this tower is actually needed, that is the question.”

Kohn Pedersen Fox Associates and Leslie E. Robertson Associates haveproposed a master plan for a new city in Tokyo Bay, a key feature of which is a mile-high (1,609-m) residential skyscraper.

One of the premises for the master plan, entitled “Next Tokyo 2045: A Mile-High Tower Rooted in Intersecting Ecologies” is the recognition that Tokyo faces a city-wide risk from rising sea levels, as well as seismic and typhoon risk. Given this, the authors argue that a strategy is needed that offers protection to the low-elevation coastal zones surrounding Tokyo Bay.

Their solution is the construction of an archipelago of reclaimed land to create a new district that would stretch 14 kilometers across Tokyo Bay between Kawasaki in Kanagawa prefecture and the shoreline of Kisarazu in Chiba prefecture (marked by the two red pins in the Google map below). Next Tokyo would create a protective border across the bay where multiple phases of land reclamation have already created a bottleneck in the bay.

I'm having a hard time matching the points on these two maps. Can someone tell me what parts of land on the 1960s map were filled and what weren't (aside from the mid-bay stuff, of course). And how does the right/2045 map differ from today?

Highly doubt that this will happen.The tallest tower in tokyo is 256 m and the jump leap to 1700m all of the sudden is illogical.Japen has taken less interest in building megatall yet alone this.What does 1700m means now?Ultratall?Supermega tall?

Putting aside the simple fact we need dreamers and unreasonable suggestions to make progress as humans, this is not a viable plan for Tokyo as many have mentioned.

Earthquakes. Reducing workforce. Actual benefits. Real needs. Lack of third world drive to build something unnecessary in a silly place to show your country / city has arrived on the international scene. Tokyo and Japan met this criteria in the early 1960s...
